Free Spins Value Calculator
Free Spins Value Calculator
Estimate what a free spins offer is worth once wagering and win caps are taken into account.
Estimates are averages over many players. Any single session can win or lose much more. The cost to qualify is the expected loss on the money you must wager first, at the same RTP. Since 19 January 2026, UK-licensed sites cannot set wagering above 10x.

How to use the free spins value calculator
Free spins offers look simple, but the headline number hides the real value. This calculator turns the terms into a single estimate in pounds. You will find every term you need on the offer page or in our guide to how free spins work.
1. Number of spins and value per spin. Most UK free spins are worth £0.10 each, so 100 spins have a face value of £10.
2. Slot RTP. Use the RTP of the slot the spins are on. If you don’t know it, 96% is a fair average.
3. Wagering on winnings. Enter 0 for no-wagering spins. Since 19 January 2026, UK-licensed sites cannot set wagering above 10x.
4. Max win cap and cost to qualify. Add the cap on winnings if there is one, and how much you must wager to unlock the spins.
Free spins calculator FAQs
Why is the estimate lower than the face value?
A slot pays back less than you stake on average, so 100 spins at £0.10 return about £9.60 at 96% RTP. Wagering and the cost of qualifying reduce it further.
Are no-wagering free spins always better?
Usually, because what you win is paid as cash. A larger offer with low wagering can still be worth more, so compare both with the calculator.
Can I lose money on a free spins offer?
Yes, if you must wager real money to qualify. The estimate includes that cost, so a negative figure means you are likely to lose more than you win.
